Bronze repair after machining

2
If you are in Australia "Old Timer Engines" in Australia. I don't know about the rest of the worls. India or UK your best bet. In desperation you may cast them in PHOSPHOR Bronze using the old ones as model (allow for some shrinkage) I made a repair time ago on my Camshaft gear with bronze and it was still here in percfect nick. One tooth was broken but not on my repair! If you are in Australia and have no workshop try the Men's Shed for machining your cast.

The timing gear on the cr'shaft was fornicated hence the big repair. All timing gear had to be replaced. Grinding down the gear gave me access to the back of the bearing, enough to catch on the plates on the press then puch down the shaft. The rest was a song. Today I just replaced the new gear and the bearing, in the press. I had to make a long pipe to slide over the shaft to reach the gear/bearing. Phew!

Done! I had to grind  the timing gear in order to make 2 ledges so I could catch it in the press. The crankshaft is 35 kg and if it were 1 cm longer I would not have been able to set it on the press. I just wish I didn't waste 2h trying to get the bearing with the hammer and chisel.

Hi! Also how to pull off the timing gear off the crankshaft (heat?)

I got the answer: Definitely take off the other side camcover! Done .. Now that pin WILL NOT come off so I am about to drill it. On the single cylinder there is a single collar to do the same retaining job as the fuel pump cam on the twin.

I asked the question my self on a new topic. The center bushing is the resist. I don't know how to free the camshaft from it, ther is no access. Yest I unscrewed the top retaining pin.

Hi everybody, I am new on this forum and pleased to be here with a bunch of fellows Lister lovers! I am in North Queensland and also on Infopop Biodiesel forum (same name)
Please somebody help: I don't know how to pull my camshaft out. Everything is down, flywheel, front cover, oil pump, tappets and push rods out of the way. Just need to pull the shaft but the center bushing is the piece that resist. The top screw pin is also removed. Do I need to open the opposite cover and chase the shaft (or pull it from the front with a puller)? If it is so hard to pull how am I going to put it back? Nothing on Yootube, Utterpower does not talk about twin cylinders, I am in the dark. I won't touch it till I know exactly the method.
Engine: CS 20 2cyl Vidhata  Thanks for considering.
